Check and adjust the engine speed of the engine idling

Because diesel engines have no ignition system requires a special tachometer. However, its purchase is not justified, since it is quite expensive. Warm up the engine to operating temperature, coolant temperature should be at least +80 ?� C.

Turn off all electrical consumers (radio, lighting). With the engine running at idle speed with the parking brake.

Measure the rotational speed of the crankshaft of the engine idling, which must be:

- (825 ?� 25) ^min -1 Engine RF;

- (725 + 25) ^min -1 Engine RF-N.

If the speed of the crankshaft of the engine idling does not match the required, loosen the locknut and turn the adjusting screw to adjust the speed (Fig. 4.24). After adjustment, tighten the lock nut.
